Lachlan W. Child, Toledo, Ohio assignor to Air- Way Electric Appliance Corporation, Toledo,

Ohio, a corporation of Delaware Application January '7, 1932. Serial No. 585,315 20 Claims. (01. 257-137) This invention relates to heaters of the type commonly known as a wall heater, and has as its object to provide a heater which may be readily installed, presents a neat appearance when installed, and is adapted to create a forced circulation of air, taking cold air into its lower region and discharging heated air in a horizontal direction at its top.

Another object of the invention is to provide a simple thougheifective arrangement for supporting a radiator in a heater casing in a position to transfer heat to a stream of air produced by a blower in the casing.

A further object is to provide for a wall heater a casing structure which will adapt itself to various type of floors, an adjustable lower or intake grille being provided which may be set so that its lower edge will contact the floor surface irrespective of the respective levels of the sup porting surface on which the base of the heater rests, and of said floor.

With theseand other objects in view my invention consists in the combination and construction and arrangement of the various parts thereof, whereby the objects contemplated are attained, as more fully set forth in the accompanying specification, pointed out in my claims, and illustrated in the accompanying drawings, .in which:

Fig. 1 is a front elevation of the heater, parts being broken away to better illustrate the construction.

Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a detail sectional view taken on line 33 of Fig. 1.

Fig. 4 is a view of the radiator bracket.

Fig. 5 is a vertical sectional view through the water trap.

Fig. 6 is a vertical sectional heater.

Fig. '7 is a similar view through a somewhat modified form of heater.

I provide a heater casing having a base comprising a bottom wall 10 and angle iron legs 11, a rear wall 12, end walls 13, and a top wall 14.

A pair of angle iron 'rails 16' and 1'7 are secured at their ends by means of screws to brackets 18 attached to the end walls 13. (See Fig. 3.) To the rear faces of the rails 16 and 1'7 is permanently secured an insulator wall 19, forming together with said rails 16 and 1'7, an integral insulator wall "unit. The term insulator is used to denote the function of the wall in forming an insulating air space.

the

view through the Radiator brackets 20 are secured between the insulator wall 19 and rear wall 12. The brackets 20, insulator wall 19, and rear wall 12, form a conduit which provides a vertically extending air passageway 21, in which is located the steam radiator 22.

Nipples 23, threaded into the ends of the radiator 22, are extended through the brackets 20 and supported by means of U bolt hangers 24. Slots 25 in the brackets 20 allow vertical adjuste5 ment of the nipples.

To one of the nipples 23 is secured a valve 26.

A steam pipe 2'7 leads to the valve 26 and extends downwardly through the bottom wall 10 in the end space between an end' wall of the casing and the radiator and blower units respectively. Similarly a steam trap 28 is attached to the other nipple 23, extends downwardly, and is attached to an elbow 29 of a steam pipe 30.

Thenipples 23 support the weight of the radiator. The insulator wall 19 and rear wall 12 hold the radiator in upright position, against tilting about the axis of the nipples 23.

In the form of the invention shown in Fig. 6, shoulder plates 31 and 32 are secured to the horizontal flanges of the rails 16 and 1'7 respectively, and extend horizontally to the plane of the forward edges of the casing.

Clips 33 and 34 are secured to the inner sides of the end walls 13, near the lower and upper ends thereof, respectively. The clip 33 is secured by means of a screw 35 extended through a vertical slot 36 in the clip and thence threaded into the end wall 13. The slot 36 allows vertical adjustment of the clip.

A front panel 37 is, secured to the clips 34. The front panel includes a grille 38 through which air is discharged from the heater. The panel 3'7 rests against the edges of the plates 32 and 31, deriving support therefrom.

The lower portion of the panel 3'7 is lapped by a lower grille 39 which is carried by the clips 33, and which holds the lower portion of the panel 3'7 against outward buckling.

The ends of the panel 3'7 and grilles 38 and 39 project beyond the end walls 13 of the casing, thereby covering the edges of the building wall definingthe cavity in which the heater is received. Similarly, the upper region of the grille 38 extends upwardly beyond the upper wall 14, covering the lower edge of the building wall.

The cavity in the building wall is outlined ,by a frame 40 including a horizontal sill provided with a downwardly projecting shoulder 41,

spaced inwardly from the wall finish panel 42.

A flange 43 projecting upwardly from the top wall 14 of the casing, engages the shoulder 41 and may be secured thereto in any known manner to securely fasten the heater in the wall cavity. The finish panel 42, of plastering or the like, may then be extended to the top wall 14 without the necessity of securing it to the heater casing.

The front panel 37 is attached after the casing has been installed in its cavity in the building wall, and overlaps the panel 42 to conceal the edges of the cavity. If it is desired to inspect or repair the interior parts of the heater, this panel may be removed by simply removing the screws 52 securing it to the clips 34. The insulator wall unit 16, 17, 19, 31, 32, may thence be removed by removing the screws 15 by means of which the rails 16, 17, are attached to the brackets 18.

It is to be noted that the panel 37, if desired, may be removed without entirely removing the grille 39, the latter being loosened just enough to allow the lower end of the panel 37 to be slid upwardly until it is, free. The insulator wall unit may be removed through the opening thus provided.

The insulator wall 19 intercepts horizontal radiation from the radiator 22, keeps the panel 37 cool, and reflects back into the air stream flowing through the space 21, most of the heat it intercepts.

The grilles 38 and 39 are kept from overheating by the flow of air through them.

A baflle plate 53 is secured by means of an integral flange 44 to the plate 32 and extends upwardly in front of the radiator unit 22 to conccal the same from view through the grille 38, and to concentrate the air stream at the top of the casing so as to increase the horizontal velocity of the air delivered from the heater.

In the space in the bottom of the casing, opposite the grille 39,.is the blower unit including the blower 45 and motor 46, the blower taking in air at the points 47 (Fig. 1) and delivering it as indicated at 48 (Fig. 6). The upper wall of the blower is positioned closely adjacent the shoulder plate 31, whereby its discharge is concentrated into the space 21.

In that form of the invention shown in Fig. 7, which is designed for thin walled buildings, the upper portion of the casing is shallower than in the other form, sufficient space for the blower being provided by extending the plate 31 beneath and beyond the panel 37, and building out the lower regions of the end walls 13. The grille 39 includes a skirt 46 which covers the plate 31 and extended portions of the end walls 13, and presses the panel 37 into contact with the edge of the rail 16.

The panel 39 has an edge of sufficient thickness so that when the heater (either type) is installed on a floor wherein the base 11 rests on a subfioor member 47 and a layer of flooring 48 may be set down to laid up to the forward face of the base 11 as shown, the lower edge of the grille 39 may rest upon the flooring 48 and conceal its edge.

When'used in connection with a mosaic or concrete floor 49 as shown in Fig. 6, the grille bring its lower edge flush with the lower edge of the base 11, as'sho'wn. To this end, the grille is slidable past the forward face of the base.

In the operation of the heater, air is taken blower and thence discharged upwardly through the radiator and thence out through the upper grille 38 in a horizontal direction, as indicated by the arrows 50.
